“Britney does not sing. She is being paid a lot of money to lip-sync,” one so-called “source” tells the newspaper. “Her fans are none the wiser, but it is disingenuous of her to take their cash and not deliver a proper performance.”

Gossip Cop hears that the supposed insider has been trying to feed this rumor to other outlets for weeks — and finally got the Daily News to bite.

A source close to Spears tells us flatly, “Britney will be singing.”

We’re told she’s been in vocal training for months, and that it will be her voice on her upcoming album — and in Las Vegas.
